Testing (#420)
* scripts: reduce pgloader's prefetched columns 

This helps fixing stack overflow errors on large
databases.

* scripts: increase the migration timeout again

It seems to be too short on some lesser-powered VMs.

* Update manifest.json

* Auto-update README

* [autopatch] Fix Host and X-Forwarded-For header spoofing
